%N A156241 Triangle read by rows, T(n,k). If k divides n then A008683(n)*A008683(k).
%C A156241 A008683 is found in the first column. A087003 appears in the second column.
%C A156241 The definition does not match the values for n=k. Apparently T(n,n) has 
               been set to 1, not mu(n)*mu(n). [From R. J. Mathar (mathar(AT)strw.leidenuniv.nl),
